JAMES ERNEST MoINTIRE, OF SOUTH FRAMINGHAM, MASSACHUSETTS, ASSIGNOR TO HOW- ARD W. BROWN, TRUSTEE.

EYE LETING-MACHINE To all whom it may concern:

Be it known that 1, JAMES E. MQINTIRE, a citizen of the United States, residing in South Framingham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanyingdrawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object the production of a novel eyeleting machine having provision for stretching that part of the stock in which the punch is to punch the hole for the reception of the shank of the eyelet, stretching the stock within the circle of the edge of the punch as the punch meets the stock to form the hole for the reception of the shank of the eyelet, serving to slightly enlarge the hole made by the punch beyond what would have been its diameter if the punch had acted upon unstretched stock.

In usual eyelet setting machines where the punching means punches a hole in the stock and does not stretch the same, the edge of the hole cut in the stock fits rather snugly the diameter of the male punch member, and as the stock is forced over the male die member and onto the eyelet, the small end of the eyelet acts to sustain the stock Where it fits the male die member, and as the cutting edge of the hollow punch member and the end of the eyelet act to cut a small cir clet of leather from the stock where it was punched by the previous action of both punch members, the cutting of the circlet enlarging the punched hole, and the circlet is forced through the eyelet and they accumulating on the setting shoulder clog the machine and prevent the correct entrance of the punch of the male die member into the eyelets and also prevent the correct setting of the eyelet.

In accordance with the invention to be herein claimed the male punch memberis extended sufhciently above the cutting shoulder of said member that the extension may enter the hollow punch member and stretch the stock before the circular cutting edge of the hollow punch member meets the shoulder referred to. In this way the stock is stretched and held stretched while it is being out, and as a result the hole left in the stock is considerably larger in diameter Specification of Letters Patent.

Referring to the drawings, A represents part of the framework of the machine, it

having a main shaft A provided with a hub end of a cross head A The edges of the cross head, see Fig. 3, are fitted to slide up and down in a suitable guideway forming part of the framework, the cross head being maintained by guide plates A held in working position by suitable screws B. The upper end of the cross head is shown in Fig. 5

as grooved to receive a holder B provided with one or a plurality of holes to receive the base B of the solid or male punch member. The holder is held in place by a set-screw B and the distance between and the number of the solid or male punch members may be varied by the use of holders provided with properly spaced sockets. An eyelet sustaining shoulder B sustains the head of the eyelet as the same is being thrust through and being set in a hole made in the stock S sustained on the stock support S. Above the shoulder B the male punch member has a cylindrical eyelet receiving shank or pen tion B of a diameter to freely enter the ey let, said portion, see Fig. 6, having a cutting shoulder 2 that coacts with the circular cutting edge or portion 3 of a hollow punch member C, the cutting shoulder 2 being made at a distance above the eyelet sustaining shoulder B greater than the length of the eyelet, and above this shoulder 2 said punch member has a stock stretching portion 4. Each male punching member is held in working position each by its own set screw a. The machine may contain any number of hollow punch members 0, each coacting with a male punch member according to the number of eyelets to be set at one operation, and as the punch members are all alike, it will be necessary to describe but one of them.

Each punch member C is held by a setscrew 0 in a suitable hole in a cross head C sustained in the portion A of the framework by a cap plate C and screws C, said cap plate having a dowel 0 shown by dotted lines Fig. 5, that enters a hole in said cross bar, and said punch members are further held against longitudinal movement by hollow screws C screwed into the holes in the cross head that receive said members. The punchings are forced upwardly through the punch C and hollow screws C. The eyelets are poured in bulk into a hopper D through a hole under a cover D, and leave the hopper to enter grooves of channel bars arranged in pairs, one or a plurality of said channel bars constituting the raceway D one or more bars being used, according to the number of eyelets to be set at one cycle of movement of the machine, the slotted upper ends of said channel bars being in communication with slots in the side wall of the hopper. The hopper has a brush-like agitator D carried by a shaft D extended through the bottom of the hopper, see Fig. 5, where said shaft is provided with a pulley D driven by a belt D, one part of which encircles a pulley I) mounted loosely on a stud D of a pivoted frame I) having a roller D that when in contact with the hub 1.2 of the pulley M surrounding loosely the hub a of shaft A turns said pulley and the pulley D and rotates the agitator in the hopper to cause the flanged or enlarged head ends of the eyelets to enter the grooves 6, 7 at the upper ends of two plates E, E constituting a channel bar for a single line of eyelets. The plate E, see Fig. 13, has a series of bottom pieces or feet 8 each fitting and turning in one of a series of circular depressions 9 of the raceway sustaining plate E leaving the open slots 6, 7 exposed in the hopper. The plate E is con nected to the plate E by suitable adjusting devices each shown as a stud screw E the flanged head of which enters a slot E in the upper edge of the plate E while the threaded shank of the stud screw enters a screw threaded hole in the plate E. When assembling the plates E, E to constitute a channel bar, see Fig. 16, the under edge of the plate E at its upper end is set on the seat 14 of the circular portion or foot 8, the edge 15 of the flanged part of the plate E abutting the edge 16 of the plate E, and the inclined upper end of the plate E as it abuts an inclined portion 17 of the foot 8, serves to lock the upper end of plate E, so that it cannot es cape due to lateral strain.

The portion E of the channel bar has at its lower end a pin 20 that enters a slot 21 or 22 of an adjusting plate 23, the drawing Fig. 12 showing three of each of said slots, oppositely inclined so that by moving said plate in the direction of the arrow, the lower ends of the channel bars may be separated farther than shown in said figure to enable the eyelets to be separated farther apart when being set into a shoe, the feet 8 at the upper ends of said bars at such time turning in the sockets made for their reception. In order that said adjusting plate may be moved when desired, I have connected with the under side of said plate by a screw 24 the lower end of a bar 25 in turn connected by a screw 26 with the inner end of a hand lever 27 pivoted at 28, said lever having combined with it a suitable locking device shown herein as a spring-controlled lever 100 having a pin 101 that may enter any one of a series of graduated holes 102 in a plate 103.

The lower ends, see Fig. 5, of the channel bars rest on a ledge 30 at the lower end of the plate E having sockets 9 entered by the feet 8 of the channel bars. The plate is mounted through bolts 31 on a sliding carriage 32 shown best in Fig. 11, the lower straight edges of which rest on shoulders 33 of tracks forming part of the frame A, the outer side walls of said carriage a little above said tracks having longitudinal grooves to receive the guiding screws 34 shown in dotted lines in Fig. 11, the inner ends of which enter said grooves and prevent the upward move ment of the carriage, but permit it to slide, as may be necessary to enable the free ends of the channel bars of the raceway to be pulled backwardly after the male punches lave risen from the position Fig. 6, and entered the eyelets, it being understood that the raceway must be moved backwardly into the position Figs. 7 and 8 in order that the male punch member may rise through the slot S of the stock support and meet the stock S laid thereon.

To move the carriage and raceway, as described, a lever G has been provided, it having its fulcrum on a stud G, the outer arm of said lever having a roller stud G acted upon by a cam G shown bydotted lines Fig. 5 and full lines Fig. 11 fast on the shaft A. The inner upper end of said lever is forked to embrace a stud Gr having its ends secured to said carriage. The stud has connected with it a spring G that normally acts to keep the carriage seated steadily on the tracks, the lower end of said spring being connected with the fulcrum G. Said lever has also connected with it one end of a spring G the opposite end of which is connected with the framework so that the latter spring acts normally to keep the roller stud against said cam and also to move the carriage and raceway forwardly, keeping the same in theposition shown in Figs. 5 and 6. The stock support has connected therewith a suitable sto or gage H that serves to position the stool; when placed in the machine and also to arrest the upward movement of the stock prior to the action of the stretching device,-said gage holding the stock as the male member of the punch rises to meet the hollow member, which is supposed to be stationary.

Referring now to Figs. 18 to 20, and to Fig. 1, (1 represents an arm or lever pivoted at cl and provided with a stud to which is connected a link (1 having a portion d notched at 40, that enters a hole or slot shown by dotted lines Fig. 3 The treadle (l is mounted on a pivot d of an upright (Z of a stand (1 erected on the floor. The inner end of the treadle is connected by a spring d with an car 112, while the stand under the front end of the treadle is provided with a stop 01. The front end of the treadle is provided with a spring-pressed pin (i the spring surrounding the pin being adjustable as to its force by a rotatable sleeve nut (1 The stand has an ear 42 on which is mounted a releasing device 43 normally acted upon by a spring 44 to kee the free end of said device toward the fu crum d. The hub e on which is mounted loosely the belt pulley M is provided with holes m, see dotted lines Fig. 18, to receive rods m, see Figs. 18 and 19, connected with a clutch collar m mounted loosely on the outer end of the shaft A, a spring m see Fig. 18, being interposed between the inner side of a nut m fixed to said shaft, and the bottom of a recess in the outer side of said clutch collar. The clutch collar has two dogs m one shown in Fig. 18, and both in Figs. 1 and 3. These dogs are adapted to enter holes on in a covering plate m shown detached Fig. 20, the same having holes m in alinement with the holes min the hub e and said plate has screw holes 44 to receive screws 45 by which to attach said plate to hub e the plate being of greater diameter than the hub and contacting with the end of the hub of the pulley M, the inner end of the hub of said pulley abutting the collar (1. The collar m has a clutch pin 45 that is extended through the hub a and the flange 0/, and presents an inclined end see Fig. 18 that is adapted to be acted upon by the wedge-shaped end 46 of the lever d, said lever when in its position Fig. 1, acting upon the end of said pin and forcing the collar m away from the plate m thus withdrawing the dogs m from the notches in in the hub a To start the machine, put the foot on the lever (i depress the same, and a portion of the lever will meet the shoulder 40 of the notched part (1 connected with the rod (1 and will depress the outer end of the lever (Z, raising the wedge-shaped end 46 so that the spring m acts immediately and permits the collar m to slide and the dogs m thereof enter the segmental spaces 48 cut into the outer end of the hub of the loose pulley, the latter at such time being rotated continuously in the direction of the arrow Fig. 19, so that the shoulders 49 of said recesses contact with said dogs and turn the shaft, the

.latter moving only for one rotation.

As the treadle is depressed from the position Fig. 3 the upper end of the spring held releasing device is acted u on by the treadle and the latter is turned in t e direction of the arrow thereon and just about as the lower end of the treadle hits the stop d, the end of said releasing device acts on the lower end of the notched part (1 and pushes the same to the left Fig. 3 against the spring-pressed pin, thus detaching the part d of the rod d from the treadle, letting the lever (Z immediately assume its position Fig. 1 under the action of a spring 50, and in this position as the shaft rotates the inner inclined end of the pin 45 meets the inclined end of the lever (Z and forces the collar m away from the rotating pulley, withdrawing the dogs wa from the inclined notches 48, 49 of the hub of the pulley, thus leaving the shaft A at rest at the end of one rotation. At times it is desired to stop the rotation of the agitator in the eyelet holding hopper, and to do this the operator will engage the handle N of the shaft N and turn the same, causing the cam n, see Fig. 11*, located at the end of said shaft to act upon a suitable portion of the pivoted frame (1 and move the same against the action of the spring n far enough to remove the wheel D from contact with the hub of the pulley M.

Fig. 1 shows the shaft in a position to show the wheel D out of contact with the hub referred to at which time the brush in the hopper will not revolve. The work support S sustained by brackets S connected with the framework by set screws S has adjustably connected therewith by suitable thumb screws S two gages S 8", one for gaging the right hand end of one half of a shoe upper, and the other for gaging the left hand end of the opposite half, said support having connected with it by screws H? the gage H be fore described. The support has a slot S through which works the male punch members. In operation let it be supposed that the raceway occupies the position Fig. 5, and that an eyelet t is sustained at the end of the raceway, as shown in Fig. 6, the male punch member occupying its lowest position, a part of a shoe top S herein designated as stock, lying on the stock support. In this condition the machine is started, the male die member is lifted from the position Fig. 6 until the portion B enters the eyelet, when the lever G is moved to slide the raceway to the right, and leave the eyelet on the portion B of the male punch member, the large end of the eyelet restin on the shoulder B. Now as the male punc member continues to rise, the stretching point 4 meets the under side of the stock, the point of the stretching member preventing the stock from slipping laterally, so that as the male punch member rises the stock is lifted and its upper side is placed against the under side of the hollow punch member 0, the stretching point pushing the stock into the hollow punch member, as shown in Fig. 7, and stretching the same, the stretching continuing until the cutting edge of the shoulder 2 of the portion B of the male punch member contacts with the circular cutting edge 3 of the hollow punch memher, when the latter coacting with the cutting edge of the shoulder 2 cuts a hole in the stock, forcing the punching 15 into the hollow punch member. After the hole is punched, the male punch member continues to rise and the small end of the eyelet enters the hole so punched, the hole being slightly larger in di ameter than the diameter of the portion B of the male punch member, that the small end of the eyelet may readily enter the hole so made, letting the stock surround the small end of the eyelet without any possibility of the cutting member 3 coacting with the small end of the eyelet, and removing a circlet from the edge of the hole punched,-as is liable to be the case if the hole is punched without the stock being first stretched, as described. During the upward rise of the male punch member after the eyelet has been forced through the hole punched, as described, the upper end of the eyelet meets the concavity i of the hollow punch member, and the cutting edge 3 gets inside of the small end of the eyelet and rolls the same over, as shown in Fig. 8, thus fully setting the eyelet. After this the male punching member is lowered and the raceway is moved back into its normal position, Fig. 5.

In Fig. 9, showing a piece of stock S, the dotted line 25 shows a mark such as would be made on the stock by the contact therewith of the circular cutting edge 3 of the hollow punch member, and said circle shows exactly the size of a hole that would be punched in the stock when said hollow punch member acts, as it now commonly does in eyeleting machines. The full circle lines i however, show the increase in diameter of the hole left in the stock after the action of the cutting edge 3 and the cutting edge of the shoulder 2, first, however, stretching the stock, as herein provided for, so that the difference between the dotted circular line i and the full line 15 shows the actual difference in the size of hole that may be left in the stock between the plan of punching the stock without stretching, and stretching the stock before punching the same.

Fig. 10 shows an eyelet 25 set in the stock. Herein the machine is stopped automatically after the insertion of each set of eyelets, this being done by the contact of pin 45 with the wedge-shaped end of the lever at, said pin as it strikes said lever being pushed outwardly into the position Fig. 18, compressing the spring and withdrawing the dogs from their engagement with the notches of the driven pulley M. The spring m is gradually depressed and acts as a cushion during the stopping of the shaft and thus doing away with the usual bumper heretofore commonly used in eyeleting machines.

Having described my invention, what I claim as new and desire to secure by Letters Patent is z- 1. In an eyeleting machine, a male die member comprising a stretching point, a shoulder at the base of said-stretching point provided with a cutting edge, and a surrounding seat to sustain the large end of an eyelet; combined with a hollow die member having a cutting edge and a surrounding setting shoulder, and with means for changing the relative positions of said members, whereby the stretching point of the male die member forces the stock into the hollow die member, stretching the same, and thereafter the cutting edge of said shoulder co-acting with the cutting edge of the hollow member cuts the stock surrounding said stretched part, thus forming a hole larger than the male die member to allow the stock to pass over the shank of the eyelet carried thereby.

2. In an eyeleting machine, a male die member comprising a stretching point, a shoulder at the base of said stretching point provided with a cutting edge, and a surrounding seat to sustain the large end of an eyelet; combined with a hollow die member having a cutting edge and a surrounding setting shoulder, and with means for changing the relative positions of said parts, whereby the cutting edge of the hollow die coacting with the stretching point of the male die stretches the stock, and thereafter the cutting edge of the said shoulder and the cutting edge of the hollow die coo erate and cut the stretched stock, forming a arge hole through which the shank of the eyelet carried by the male die member passes, and thereafter at the end of their effective stroke the seat and setting shoulder of the respective dies upset the eyelet in the hole cut in the stock.

3. In an eyeleting machine, an unyielding male die provided with a stretching point and a cutting edge, a stock support, a hollow die member having a cutting edge, and means to move said male die member to raise the stock from the stock support, force that part of the stock to be removed into the hollow die member, said dies thereafter coacting to cut the stock while stretched thus forming an enlarged hole in the stock.

4. In an eyeleting machine a hopper provided with a discharge slot or opening, a

plate located adjacent said opening and provided with a series of sockets, a series of channel-bars having at their upper ends feet to enter said sockets, and allow the channelbars to pivot therein, and means for adjusting the position of the delivery ends of said channel-bars. V

5. In a machine of the class described, a raceway presenting channelbars, one of which has a slot and an inclined end, while the other has a foot and an inclined shoulder substantially as and for the urpose specified. In testimony whereof, have signed my name to this specification, in the presence of two subscribing witnesses.
